PROBLEM TO BE SOLVED: To provide an air cleaner capable of realizing miniaturization of the device while securing an effective humidification distance between a spray nozzle and a medium.SOLUTION: A housing 500 has an intake port 502 of a ventilation path 52 open toward a lateral direction at a lower position corresponding to a medium 506, and has an air supply port 503 of the ventilation path 52 at an upper position with respect to the medium 506. An airflow route conversion region A to convert an airflow route of the air to be humidified from the lateral direction to an upward direction, is formed between the intake port 502 and a housing inner face opposed to the intake port 502, the medium 506 is disposed on the airflow route conversion region while inclined with a downward gradient, an upper end 502a of the medium is positioned closer to a housing inner face 500b provided with the intake port 502, a medium lower end 502b is positioned closer to a housing inner face 500a opposed to the intake port 502, a spray nozzle 531 sprays spray water W from an upper position of the medium upper end 502a toward a medium lower end 502b, and the spray water is scattered along a medium upper face.SELECTED DRAWING: Figure 2【課題】噴霧ノズルとメディアの間に有効加湿距離を確保しつつ、装置の小型化を実現した空気清浄装置を提供する。【解決手段】ハウジング５００は、メディア５０６に対応する下方位置に横方向に向けて開口する通気路５２の吸気口５０２を有し、メディア５０６より上方位置に通気路５２の送気口５０３を有し、吸気口５０２と吸気口５０３に対向するハウジング内面との間に加湿対象空気の気流進路が横方向から上方向に変転する気流進路変転域Ａを有し、メディア５０６は、気流進路変転域に下り勾配に傾斜して配置し、メディア上端５０２ａが吸気口５０２を設けたハウジング内面５００ｂ寄りに位置し、メディア下端５０２ｂが吸気口５０２に対向するハウジング内面５００ａ寄りに位置し、噴霧ノズル５３１は噴霧水Ｗをメディア上端５０２ａの上方位置からメディア下端５０２ｂに向けて噴霧し、噴霧水Ｗはメディア上面に沿って飛翔する。【選択図】図２
